12.7mm does it deserve the range?

HI Andy
Well actually Im not asking for cannon ranges to be increased. Im asking for 12.7, 13.2 and 15mm calibre machine guns to have their range reduced from 2000 to 1500m, In line with the rest of the games open sighted MGs.
Also When I say area fire I mean the beaten zone created at extreme range by Heavy MGs. This only occours at ranges greater than the current in-game limit for MG fire of 2000m. ie I am talking about "indirect" MG fire. Z fire is blind fire, we could quibble about the naming here all day but blind fire is not what I meant.
Anyway neither of these two points is particularily relevant.

I can understand that giving some LVTs armour of 1 instead of the correct 0 was for the game purpose of making them less sinkable. However I am at a loss as to what the game purpose would be for giving the 12.7mm calibre a bonus 25% increase in range. Would you be able to tell me what that game purpose is?
Best Regards Chuck.
